Abstract
In order to study the influence of water hammer on the safe and stable operation of the main cooling system of sodium-cooled fast reactors,the transient water hammer characteristics of the system under different working conditions were studied with the help of numerical simulation software.The results show that the system does not have water hammer when the pump is stopped and the valve is not closed.When the valve is closed instantaneously in one branch,serious water hammer will occur in all branches;Water hammer is most pronounced in the line when the valves of both the pump and all branches are closed at the same time,and can be attenuated by extending the closing time,the time between closings,or the addition of new equipment before and after the valves.Finally,recommendations are put forward to prevent and reduce water hammer from the design,construction and operation stages of the reactor.关键词
